Printed the first prototype of the intake over the last few days. Had no issues printing it, but I had to cut it up in 7 parts to be able to print it without issues. I'll do a test fit today if the weather holds up.

I've done more extensive testing of this. I started simulating flow, even pressure over the throttle body etc. I finally have the design ready. I took me many revisions to get the flow even. The design is 100% organic, so I had to make the adjustments by hand for every revision.

I finally ended up with this design. My first cold air intake for the Miata NB is finally done! meow I have to print it in ABS and do some testing!
